Standard scores are most commonly called z-scores; the two terms may be used interchangeably, as they are in this article. Other equivalent terms in use include z-value, z-statistic, normal score, standardized variable and pull in high energy physics.

In statistics, a standard normal table, also called the unit normal table or Z table, is a mathematical table for the values of Φ, the cumulative distribution function of the normal distribution. It is used to find the probability that a statistic is observed below, above, or between values on the standard normal distribution, and by extension ...
A Z-test is any statistical test for which the distribution of the test statistic under the null hypothesis can be approximated by a normal distribution. Z-test tests the mean of a distribution.
A z-score measures the distance between a data point and the mean using standard deviations. Z-scores can be positive or negative. The sign tells you whether the observation is above or below the mean.
Το Z-Score, γνωστό και ως πρότυπο αποτέλεσμα, είναι μια στατιστική μέτρηση που υπολογίζει τον αριθμό των τυπικών αποκλίσεων που μια δεδομένη ακατέργαστη βαθμολογία είναι πάνω ή κάτω από τον μέσο όρο.
29 Δεκ 2023 · To find the Z score of a sample, you'll need to find the mean, variance and standard deviation of the sample. To calculate the z-score, you will find the difference between a value in the sample and the mean, and divide it by the standard deviation.
7 Ιαν 2024 · The z-score. The number of standard deviations from the mean is called the z-score and can be found by the formula. z = x − m σ (1) (1) z = x − m σ. Find the z-score corresponding to a raw score of 132 from a normal distribution with mean 100 and standard deviation 15.
